3 Claims.

This invention relates to an improved window and screen assembly.

An object is to provide an improved window and screen assembly which is. particularly adapted to be used as a storm window and screen assembly placed within the window opening in a building outside of conventional upper and lower sliding window sash. The assembly might be used, however, in lieu of the usual conventional upper and lower sliding sash instead of as a storm window and screen assembly supplemental thereto.

An object of the invention is to provide such an assembly which is formed entirely or in large part of sheet metal parts and which is so constructed as to be adjustable within limits to fit a window opening. Window openings designed to a definite dimension vary slightly in size both horizontally and vertically. It is a purpose of this construction to provide a structure which is adjustable to fit openings which vary slightly in size. The sheet metal parts which make up the construction are adjustable within limits to provide for this variation in size of window openmgs.

Not only are adjustable jamb strips provided to fit the assembly to window openings of different horizontal dimensions, but the sill portion of the window frame assembly is particularly designed for adjustment either vertically or horizontally to facilitate fittin the assembly to window openings which vary as to dimensions vertically and horizontally and which also form a tight seal with the sliding ash mounted within the frame assembly.

Another object of this invention is to provide a window assembly of the character described wherein upper and lower sliding window sash are provided and a screen sash is provided and wherein the window sash and screen sash may be readily inserted or removed for cleaning or repair. The construction is such that the window panes may be cleaned without removal of the sash from the frame assembly or the sash may be quickly removed for the cleaning of the panes. The construction is such that these operations may be carried out quickly and easily.

A meritorious feature is that the opposed jamb portions of the window frame assembly which exhibit the guide channels for the upper and lower sliding sash comprise upper and lower sections which meet at about the meeting rail'juncture of the sliding upper and lower. sash elements.

The upper sections of the two jamb portions are removable to facilitate removal and insertion of the sliding sash elements mounted between the lamb portions.

Another meritorious feature is that each of the two opposed complementary jamb portions is formed of a strip of sheet metal bent to exhibit an outwardl open channel adapted to be snugly removably received over a side frame member of the assembly or over a stop fixed within a window opening. Such jamb portion is also shaped to exhibit a pair of guide channels disposed on opposite sides of the first mentioned channel and facing inwardly and which serve as guide channels for sliding upper and lower sash elements.

Another important feature is that the upper and lower sash elements are provided at their meeting rails with projecting overlapping flanges adapted to be brought resiliently into engagement just before the upper sash i completely elevated and the lower sash is completely lowered so as to form a tight weather seal.

Another important feature is that the overall vertical dimension of the upper and the lower sash when such flanges are brought into initial engagement is somewhat less than the overall vertical dimension of the guide channels within which such sash are mounted. When upper sash is completely elevated and the lower sash is moved to its lowermost position it will pull the upper sash slightly downwardly but without withdrawing the upper rail of the upper sash from the header recess in the frame. This slight downward movement of the upper sash by the lower sash will urge the upper sash against the top of a screen mounted within the frame assembly below the upper sash locking the screen in position.

More particularly the construction is ofsuch a character that a screen element can be mounted within the frame assembly and designed to cooperate with the upper sash so as to hold it elevated and locked within the elevated position against tampering from the outside of the window. Such screen may be removed from the inside of the window by raising the lower window sash and then elevating the screen and upper sash slightly so as to permit withdrawal inwardly of the screen. Specifically the flange of the upper sash is shaped to seat over the top of the screen.

Another feature of importance is that the frame assembly is provided alon the sill with a resilient inner stop portion over which the screen may be moved for insertion or. removal thereof,

and which stop bears against the inner face of the lower rail of the screen when the screen is in place. Such sill portion of the frame is also proform in Figs. 1 throughl2.

Or for repair.

vided with an outer stop element adapted to engage the lower rail of the screen on the outside when the screen is in place. These inner and outer stop elements on the sill of the frame are adapted for ready removal for disassembly purposes and also form weather tight seals with the screen.

The sliding window sash are frictionally gripped by the side walls of the guide channels within which they are mounted to maintain adjusted positions vertically therein, but in addition the screen is adaptedto be employed to retain the upper sash in the elevated position against unauthorized lowering. The assembly may be left in the window opening the year around or may be removed as desired. The assembly may be used with or without the screen.

Other objects, advantages and meritorious features will more fully appear from the following description, claims and accompanyinng drawings, wherein:

which also may be readily inserted from the inside of the building into position underneath the outer elevated sash or removed therefrom. The lower sash may be elevated so as to expose the screened opening.

The frame assembly includes in Figs. 1 through 12 opposed complementary side frame members 28 here illustrated as formed of Wood and con nected at the top by a header member 22 and connected at the bottom by a sill member 24. These two opposed side frame members 20, header member 22, and sill member 24 form a frame of a. generally rectangular shape adapted to fit a conventional window opening. A header portion formed of sheet metal is shaped to exhibit a channel 26 which is open upwardly to seat over the header frame member 22 as shown particularly in Figs. 3 and 8. This header member is shaped to also define a downwardly open chan'- nel portion 23 which is disposed on the outside of the window frame. The outer side wall of this channel 28 slopes inwardly toward the upper sashas shown in Fig. 3. The header portion channel 26 is of such a size as tobe snugly re- Fig. 12 is a perspective from the inside showing theremoval of the lower sash after the upper sections of the jamb-portions have been removed. 1 Fig. 13 is a fragmentary perspective of a modification as compared with the construction of Figs. 1 through 12.

My window assembly is shown in preferred It consists of a storm window and screen assembly adapted to be inserted within a window opening of a building outside of conventional sliding sash with which such opening is'ordinarily fitted. My assembly is designed without any cutting or adaptation by a carpenter to bereaclily adjusted'to fit openings which mayvary slightly in size. Window openings designed to a determined size vary slightly in dimension. My assembly is provided with filler or sealer strips at the sides and at the bottom which are adjustable to permit the assembly to be fitted to openings, of slightly different dimension.

My assembly is built up primarily of sheet metal pieces formed and fitted together in such a manner that it is readily possible-to remove either'or both of'the sliding sash from the inside of the building withoutremoving the. assembiy from the window opening; The sash maybe readily removed for cleaning-of the window panes The assembly includes a screen ceived over the header frame member 22 and is adapted to grippingly engage the same to maintain its seat thereupon. I

A sill portion is also formed up of sheet metal. This sill portion exhibits a downwardl open channel 30' adapted to seat over the sill frame member 24 as shown particularly in Fig. 5 and Fig. 9. As shown in Figs. 5 and 9, this sill portion has a; horizontal ledge 32 which projects toward the inside of the building. This ledge 32 has a margin 3A which projects upwardly and outwardly toward the lower sash as shown in Fig 9. This marginal flange 34 is adapted to engage the bottom rail of the lower sliding sash as shown particularly in Fig. 5.

The sill portion is so shaped as to'eXhibit on the outside of the window assembly an upwardly open channel 36 which depends over the outer face of the sill frame member 24. The side wall of this channel which is adjacent to the sill frame member 24 is spaced slightly therefrom as shown in ,Fig. 5. A sill filler strip or weather strip 38 of angular cross-section'and formed in two sections is received between this inner wall of the channel 36 and the sill frame member 2d as shown particularly in Fig. '5. This filler strip 38 is grippinglyheld by the side wall of the channel sill portion 36 against the face of the sill frame member 24. It is adjustable up and down to bring its flange portion 49 into abutment with the stationary sill of the window opening. This sill filler strip 38 is, as stated above, formed in two sections, identified in Fig. 1 as 38 and 38a. These sections overlap at their meeting ends as there shown. They are telescopically horizontally adjustable to fill out the required width which the window assembly is bottom rail of'screen element 44.

There is" an outer stop 46 which has a leg portion that is also receivable within the channel 3t asshownin Figs. 5 and. 9. 'This stop ele-.

ment has an outwardly downwardly bent marginal flange or roll 48 which overhangs the upper margin of the outer wall of the channel 36 and forms a weather seal. This roll also forms an outer stop for the same screen element 45 as shown in Figs. 5 and 9.

The window assembly includes opposed complementary upright jamb portions illustrated particularly in Figs. 1, 2, 3 and 8 of the drawings. Each jamb portion is formed of sheet metal. Each jamb portion exhibits a pair of runway channels. There is an outer runway channel 52 and an inner runway channel 54. The outer runway channels and the inner runway channels on the two jamb portions are complementary as shown particularly in Fig. 6. Each jamb portion is so formed that the two runway channels 52 and 54 are spaced apart by a channel 56 that faces in the opposite direction from the runway chan nels. The two side walls of the channel 56 are common with the inner side walls of the runway channels 52 and 54 as shown particularly in Fig. 3. The channel 56 of each jamb portion is adapted to be snugly received over and grippingly engage a side frame member as shown in Figs. 3 and 6 so as to secure the jamb portion thereto.

There is provided for each jamb a filler strip 58 which is angular in cross-section as shown in Figs. 3 and 6. This filler strip has one leg that is received alongside of the side frame member 26 within the channel 56 of the jamb portion and is held grippingly by one side wall of such channel against the side frame member 20. This filler strip is capable of being pulled outwardly from the-closed position shown in solid line in Figs. 3 and 6 to a dotted line position shown in Fig. 6 for adjustment of the frame assembly to fit window openings of diiferent width.

'two sections meet at about the point of juncture of the meeting rails of the upper and lower window sash. The outer side wall of the inner runway channel 54 is cutaway at the top as at 60, Fig. 2, somewhat below the top of the inner side wall of such channel to facilitate removal of the lower sash therefrom.

The two upper sections U of the jamb portions are capable of being removably withdrawn from the jamb frame members 20 as shown in Fig. 8 when the two window sash are dropped down between the two lower sections of the jamb portions. They are withdrawn interiorly of the window frame. This can be accomplished'from the inside of the building without removing the window assembly from the window opening.

When this has been done, the upper and lower sash may be readily removed. These upper and lower sash may also be removed from inside of the building and without removing the assembly from the window opening.

The upper sash is indicated by the numeral 62. The lower sash is indicated by the numeral 64. The upper sash is slidably supported for up and down movementwithin the runway channel 52 of the two jamb portions. The lower sash is slidably supported 'for up and, down movement within the runway channel 54 of the two jamb portions. Each runway channel is so formed that its outer side wall bears resiliently against the sash so that the sash is maintained at any position at which it may be raised or lowered within the runway channel.

My assembly includes the upper and lower sliding sash 62 and 64 and the screen and the arrangement is such that when the screen is in position as shown in Figs. 1, 4 and 5 it is held in such position by the upper sash bearing against the top rail of the screen as shown in Fig. 7. Each of my sash elements as illustrated is pro vided with a pane held in metal sash. The bottom rail of the upper sash exhibits a channel 68 which receives the lower margin of the glass pane as shown in the drawings. This bottom rail is then bent inwardly and downwardly as at 1B and its margin is bent downwardly and upwardly and folded upon itself as at 12. The portion 10 defines a downwardly opening recess or groove extending lengthwise of the bottom rail and within which the top rail of the screen 45 is adapted to seat as shown particularly in Fig. '7. The bottom rail of the screen is seated between the marginal flange 44 of the inner stop 42 and the marginal roll 48 of the outer stop 46 as shown in Fig. 5. In this position, the screen is held securely in place.

The marginal portion 12 of the bottom rail of the upper sash is adapted to be received within the downwardly open groove formed by the downwardly turned margin 14 of the upwardly bent flange 16 of the top rail 18 of the lower sash 64. This engagement of the meeting rails of the two sashes locks these two sashes together as shown in Figs. 4 and 7. It is not possible to remove the screen either outwardly or inwardly when the two sash elements are interlocked together as shown in Fig. 7. The weight of the lower sash supplements the weight of the upper sash in holding the screen down and the bottom of the screen cannot be moved laterally because it is engaged between the inner and outer stop elements 42 and 4B.

The interlocking flange portions 12 and 14 of the meeting rails of the two sashelements resiliently engage each other as the lower sash is lowered before the lower sash is'completely lowered into place as shown in Fig. 5. The overall dimension of the two sash elements 62 and 64 when interlocked as described is somewhat less than the vertical dimension inside the window frame assembly so that the top rail of the upper sash may be raised into the header channel 28 'of the header portion sufiiciently to permit the bottom rail of the screen to be moved over the marginal flange 4a of the inner stop 42 to position the screen between the stop elements 42 and shown in Figs. 5 and 9. The screen may then be dropped down into position between these two stop elements. The upper sash may then. be pulled down against the top of the screen.

The header channel 28 possesses sufficient depth topermit this partial lowering of the upper sash, for example asshown in Fig. 3, without releasing such upper sash.

To insert the screen, the upper sash is completely elevated and the lower sash is also raised. The screen is then inserted from the inside. Its bottom rail is moved over the marginal flange 44 of the inner stop and dropped into position between the two stop members as shown in Fig. 5. The lower sash is then lowered. The flanges I2 and 74 of the meeting rails of the two sash elements come into engagement before the lower sash is completely lowered and pull the upper sash down snugly against the top rail of the I away of the sidewalls as at 69.

screen as shown in Figs. 4. and 7. The lower sash may then be raised as desired and the screen is held securely in place. The lower sash is provided with a channel 80 having an inwardly downwardly turned marginal portion 82 adapted to serve as a handle in the raising and lowering of the lower sash.

Not" only may the screen be inserted or removed rom the assembly from the inside of the building and without removing the assembly from the window opening, but the two sash elements may also similarly be removed or inserted. To remove the sash elements, the screen is first removed as hereinabove described. Both sash elements are then lowered. The upper sections U of the jamb portions may then be withdrawn inwardly as shown in Fig. 8 and removed from the side frame members 29. When these two upper jamb portions have been removed, the lower window sash 64 may be elevated out of its channel 54 and completely removed inwardly. The inner side walls of the runway channels 54 are cut away at the top as at 60 as shown in Fig. 2 and as hereinabove described and this allows sulficient clearance for the removal of the lower sash inwardly. As the structural unit is shown in Figs. '1 and 2, it would of course be possible to lift the lower sash 64 upwardly directly out of the runway channels 54 even though they were not cut away at 55 because there would be plenty of room for upward movement of the lower sash, but when the assembly is mounted within a window opening, this upward movement is limited by the header of the stationary window frame of the opening and this accounts for the cutting When the lower sash has been removed, it is then possible to elevate the upper sash out of its runway channels 52 and to remove the same inwardly through the window opening. This can be done from the inside. Both sash elements can be replaced from the inside. The entire assem; bly may, therefore, be permanently secured within the window opening.

On the other hand, as heretofore stated, the assembly frame members 29, 22 and 24 may be permanent stops permanently secured within the window opening and header, sill and jamb portions 26,. 30 and 56 may be mounted thereon in the same manner as is here shown. In such case, there would not of course be provided the jamb filler strip 58. Such a structure is shown in Fig. 13.' a
